Abstract:Objective To assess the clinical effects and safety of microscope assisted minimal invasive surgery-transforaminal lumbar inter-body fusion(MIS-TLIF) in the treatment of lumbar degenerative disease. Methods From January 2016 to January 2017, 160 patients of lumbar degenerative disease were retrospectively analyzed. Eighty patients underwent TLIF (the control group) and 80 patients underwent microscope assisted MIS-TLIF (the observation group). Clinical evaluation: visual analog scale(VAS), Oswestry disability index (ODI), blood loss, postoperative drainage, X-irradiate time, length of hospital stay and interbody fusion rate. Results The surgical incision length was (3.7±0.8) cm in the observation group and (8.2±1.5) cm in the control group. The blood loss was (63.2±30.3) mL in observation group and (170.6±21.4) mL in control group. The postoperative drainage flow was (22.1±10.7) mL in observation group and (80.2±20.3) mL in the control group. The X-ray exposure time was (26.1±3.7)s in observation group and(16.5±4.2)s in control group, There were all significant differences between the two groups(t=23.680, 25.902, 22.651, 15.343, all P values<0.01). The VAS scores (0.68±0.41 vs. 1.95±0.64, t=14.950, P<0.01) and the ODI (7.29%±3.60% vs. 12.70%±4.27%, t=8.664, P<0.01) showed significant differences between the observation group and the control group at one year of follow-up.The incidence of complications in the observation group was lower than that in the control group(P<0.05).The rate of intervertebral bone graft fusion in the observation group was higher than that in the control group(P<0.01). Conclusions MIS-TLIF assisted by microscope is a safe and effective treatment for lumbar degenerative disease. Patients with this operation have less traumas and recover faster after operation. Microscope assisted TLIF is worthy of clinical promotion.
